So what do you hope you would have the courage to do? Faithfully carry out God’s command through Moses, or refuse to follow orders?
Wow. A LOT to read here, for certain. I would like to respond to the original poster's question(s), though, if I may (may you all have peace!). Thank you!
All of the arguments as to what may or may not have actually occurred... and why or why not... notwithstanding, I would do what my Lord would have taught me then... and has taught me. As Moses did on behalf of rebellious, murmuring Israel just three days out of Egypt... as Abraham did when told the fate of Sodom and Gomorrah... as Jeremiah did when told what was to come upon Israel and Jerusalem... and as my Lord himself did when they pierced him: I would plead on behalf of the people... even though they were my enemies... that they be shown mercy. And then I would leave the ultimate choice, decision, act to the Most Holy One of Israel Himself to carry out... if He indeed chose to do so. I would NOT, however, raise MY hand against a single one... nor would I allow ANY of MY family members to do so (to the extent that was within my power).
As to my implied "disobedience"... I totally disagree that it would BE disobedience. Rather, from what I know now it would be OBEDIENCE... to the REAL Covenant based on the Law written on hearts: the Law of Love... even of one's enemies.
And in case He asked me (and I've no doubt He will because, if you take note, that is one of the primary ways the Most Holy One of Israel, indeed all spirit beings, communicate... by asking questions - although they do state things, many things, as well), I would as humbly and kindly as I could... remind the Most Holy One of Israel that although I know vengeance indeed belongs to Him, I know... even moreso... that it does NOT belong to ME. I would then also remind Him of His Law as to ME... and humbly and kindly ask that me and MY family be shown the same mercy I am now showing toward those who SHOULD be devoted to destruction... but whom I do not judge (because my Lord, His Son, has taught me to forgive, just as HE forgives)... because I, too, exist in sin and error and should be devoted to destruction.
I would then put faith in His Word, Christ... who has said to me that by so refraining, showing mercy, and asking for mercy me and my household WOULD be shown such mercy... though HIM... and not have our failure to carry out the command counted against us... as "disobedience".
All of this I would base on HIS (the Most Holy One of Israel, JAH of Armies) covenant with ME... which covenant is ratified by the blood of Christ... which blood I will have splashed on the "doorpost" of MY "temple"... so that He is OBLIGATED to keep it with me. Because I, for my part, will have kept MY covenant with HIM... having been obedient to the TRUE "law"... of love. And so I have NO doubt He will keep His... with me.
Seriously, that really is how I would handle it. I do not mean to sound self-righteous or "perfect"... or anything like that. I am neither. I just know what I would do... because I know me... I know Christ... and so, God, through Christ... I know the "person" he (Christ) has taught me to be... and why... and which "order" it REALLY is that I am to "carry out" in a situation like this.
Again, I bid you all peace!
A slave of Christ,
